MTR DI-3:

1 channel active DI Box.

Our opinion: Simply the best value in active DI's on today's market. Very clean, sturdy and flexible DI box perfect for sending various signals into your mic preamps.

The DI-3 single channel D.I. box has a mono jack input and link out socket, a ground lift to eliminate hum loops, a three position attenuator for accurate level matching, and a balanced 600 ohm XLR output.

The active electronics have a purely resistive high input impedance, and so do not colour the sound.

The DI-3 can be powered in 3 ways: by a 9 volt battery, phantom power from the desk (or an MTR PPS-48), or an external 9v regulated power supply.

The DI-2 is a two channel version of the DI-3 in the same sized box, for use with stereo keyboards or two separate mono signals.

It can also be used as a balanced signal splitter by connecting a short jack-to-jack lead from the link socket of channel 1 to the input of channel 2. Channel 1's signal will then be available on both balanced XLR's, and channel 2's link socket. The attenuation switches remain working independently.

Two separate main stereo inputs on ¼" jacks, plus a stereo Auxiliary input feeding stations 1 and 2 (or any combination of all six by simple internal re-wiring). This Auxiliary signal is added to the main inputs, and can be used for click tracks, talkback from the control room for more effective communication between the engineer/producer and musicians, rehearsing to a tape/CD/minidisc, etc.

A two-colour led is fitted to each of the three inputs: green=signal present, red=close to overload.

The Main Input B also has bass and treble boost and cut.

Each of the 6 headphone outputs has its own volume control, an input A or B selector button, and a mono switch sums the left and right signals.

The rear panel has duplicate input sockets for easy rackmounting.

Very solid all-steel construction

Note: the IEC mains lead is not supplied as the plug needs to match your country's power sockets. We can supply European IEC cables, please inquire before ordering.

Our opinion: A 2 channel version of the HPA-6 with a simpler EQ circuit, perfect whenever clean, reliable and powerful headphones monitoring is required.

Derived from our HPA-6 model, this smaller stand-alone version has one stereo input and one Aux. input on ¼" jacks, a Loudness button, and two headphone outputs, each with a volume control and a mono button.

Mains powered, with a rear panel on/off switch and fuse.

Multiple units can be scattered around the studio, and the Aux. input allows the musician to set his own level relative to the foldback. Also used by club DJs with mixers having an inadequate headphone amp.

As used by the BBC, Associated Press Television News, Television Systems Ltd (ITV Anglia, Tyne Tees, ITV West (Bristol), etc.

Note: the IEC mains lead is not supplied as the plug needs to match your country's power sockets. We can supply European IEC cables, please inquire before ordering.

The PS-8v is an 8 output, one stereo jack input headphone splitter. The sockets are pcb-mounted, and there is an internal link to mono the unit. Used for example, for splitting headphone signals in music rooms, computer music recording systems and hi-fi systems.
